APPARATUS FOR MAKING TIRE BEADS.

Application i led October 6, 1922. Serial No.- 592,778. n

A. DENMIRE,

' a citizen of the United States, residing at `Akron, county of Summit,`and State of Ohio, have invented certain new and useful Ilnprovements inApparatus for Making Tire Beads, of which the following is aspeciication.

My invention relates to apparatus for making tire beads. Tire "beads, ofthe socalled straighty side variety with which my invention isparticularly concerned, comprise vertical face.

stitched into the angle formed by the lateral y face and the verticalface of the form, and

a fabric covering strip surrounding convolutely 'wound strips ofnon-stretchable ma- "teriahusually in the form of a wire tapeimpregnated with rubber, and a rubberller strip. This structure issemi-vulcanized in ja mold to compress it, in cross-section, intosubstantially triangular form. Prior lto my invention, onemethod ofconstructing these beads has been to build them up on an annular form,comprising alateral face and a The fabric covering is the filler stripare wound upon the covering manually while the form is being rotated.The edges of the, covering strip are then folded over the other stripsthe wire tape and -by'the operator and rolled or stitched by a handtool. V rious and time consuming. produce sizes ofv beads of uniformcross-section and the covering becomes wrinkled and vis pinched duringthe subsequent This method is extremely labo- `molding operation.Moreover, it is difficult to vimpose a. uniform tension upon the tapeand filler strip as they are wound about the covering, which is anotherfactor that causes the covering to wrinkle and prevents the operatorfrom producing beads of uniform sizes. f

v It is the'particular purpose ot' the preslent invention to provide anapparatus l whereby straight side beads of uniform sizes may heconstructed.expeditiously and accurately, and the number of operationsreduced. l

It is also the purpose of my invention to provide for effecting auniform tension upon all the strips comprising the bead, as' they `arepositioned relatively to each other and to smooth and iron the beadstructure tov unevenness in the covering.

In the operation of the apparatus herein shown for makingr the straightside beads, I first Wind, under tension, a strip of flexible material 1,such as the usual bead covering fabric cut on the bias, into the form ofan annulus, comprising, preferably, a single convolution having its endsoverlapping. The annulusv may be formed from a single strip, or takenfrom a continuous' strip, and cut to the proper length, as Willpresently appear. I next Wind a strip of Wire tape 2, that isimpregnated with rubber, circu1nferentially of the annulus While thetape is under tension and the annulus .is being; rotated. Preferably, 1first Wind two convolutons of the tape 2 about the annulus, after whichI Wind a third convolution of the tape 2 together with a singleconvolution of a rubfer filler strip 3 about the two aforesaidconvolutions of tape. The structure thus formed is now rotated? and theedges of the fabric strip 1 are nextfturned up, or folded, over theconvolutions ,of the tape and the ller while the annulus ,is beingrrotated, to Simultaneously with the Afolded structure in such mannerthat the fabric is ironed out, both upon the sides and upon the outerperiphery of the bead. The bead thus far formed may now be molded. andvulcanized into the desired cross-sectional contour.

' The apparatus which l preferably employ in practicing the methodabove-described will nonr be set forth in detail.

The numeral 4 designatesa base of a casting having; at one end thereof,a bifurcated upright 5. At its upper end, a transverse shaft 6 isjournaled in the upright 5, said shaft being provided with a sprocketwheel' fast thereon. The sprocket wheel 7 is driven by a chain 8 thatengages a second sprocket Wheel '9 upon the shaft 10 of a speedreduction device 11. The sprocket Wheel 9 is carried by a clutch device12 which may be clutched to, or released from, the shaft 10'by means ofa collar 13. The

, collar 13 is slidable longitudinally of the shaft 10 to aetuate aplurality of clutch operating dogs 14 which carried by the clutch member12. This form of clutch is Wel-l known and forms no particular part ofthe present invention. lt will, therefore, not be described in furtl'xerdetail.

The collar lil is moved longitudinally of the shaft l() by means of abell crank lever messie the clutch elements 12, 13, 14 and17, thev bellcrank lever 15, the bar 16 and the treadle 19 is such that when theforward end 20 of the treadle 19 is depressed, the

clutch Will be actuated to lock the .sprocket n Wheel 9 to the shaft10aud thus rotate the shaft 6. A retractile spring 21 is connected atone end to the bell crank lever, as at 22, see Figure 3, and has itsoppositie end connected to an upright 23 arising from the base 4.I Thespring 21 serves to normally dsengage the clutch element 12 fron'i theshaft 10 and to hold the treadle 19 with its forward end in `raisedposition.

At the rear of the casting 4, a pair ofuprights 24, one of which isshown in Figure 1, are provided. Between the uprights 24, a reel 25 isjournaled for rotation abbut an axis parallel with the shafts 6 and 10.The reel 25 is adapted to contain a roll of the Wire tape 2 and isconstructed to provide spaced annular side members, one of which isshown at 26. A brake band. 27 is arranged about the periphery of one ofthe members 26, Dreferably in the manner shown in Fig,` ure 1, whereinone end of the band is connected, as at 28, to the casting 4, `while thefree end of the band is provided with a Weight elcn'lcnt 29. The weight29` is supported upon one ond of a lever 30 which is fulcrumedintermediate its ends, as at 31, upon the base member 4. The oppositeend of the lever is connected for sliding engage- :ment with theintermediate portion of the lever 19. The arrangement of the levers 30and 19 is such that when the lever 19 is depressed to effect rotation ofthe shaft 6, the Weight 29 is lifted to decrease the -retardingV effectof the baud 2T upon the reel 25, so that by this means the tension uponthe strip 2 is relieved as it is pulled `from the reel 25. Above theveel 25, an idler roll 33 is journalcd upon the uprights 24, over whichthe tape 2 passes as it vis takenfrom the reel 25. Tape of thc characteremployed in building beads is coated with rubber and therefore is tackyand is usually wound with a liner, l', therefore, provide a liner reel34 also journalcd on the uprights 24 for reeling;f up said liner as thetape is pulled from the reel 25. A reel 35 is journaled upon theuprights 24, as shown in Figure 1.

The reel l5 is ,lesignmd to contain' the strip` vided Vwith a brakev'drum 36 over: which a brake band 3T is trained. 'One end ofthe mannerof mounting th'e'reel 35, I effectV a tension upon the filler strip 33as it 4is pulled from the reel.

table 40 intermediate the upright`5 and the uprights 24. Upon thistable, the strips of covering material l may be assembled into acontinuous strip, if desired, but preferably I-` employ a reel 4lkofcovering material corniv prising a continuous stripf .Reel 4l isjouranaled preferably beneath the table,` and the material therefrom isled over an upwardly inclined guide 42 toward the upright 5. The ends ofthe strips 2 and 3 are likewise led through guides 48 arising from thetable 40 toward the upright 5, as will be apparentV fromA an inspectionof Figure l. f

The free ends of the strips 1, 2 andl 3 are designed to be wound aboutan annular form 44 that is fixed upon the shaft 6 for rotationtherewith, which form comprises a wheel 45 having an outwardly extendingflange 46. A ringor annulus 47, having radial lugs'48, is adapted to bepositioned upon `the wheel 45, with the lugs 48 abutting the flange 46of said wheel. Screws 49 are provided at suitable intervals in the rimof the wheel 45 to engagethe lugs 48 and hold the annulus 47 in place.The form 44 is constructed in this manner so that annuli yof differentthickness may be positioned thereon. and different sizes of beads builtup on the form. Preferably each annulus 47 is provided with acircumferential centrally located rib 5() hav-ing a transverse face 51and Vertical side faces 52. The rib 50 is approximately the'width of thebead' which it is desired to build, and the annulus is constructed toprovide' the horif zontal face 53 upon 'each side of said rib 50 for a'purpose presently apparent.

A rectangular shaped bracket 54 is suit-L, ably affixed to the standard5 to project lat-y erally therefrom upon each side of the' shaft 6.djacent one end of the bracket 54, an L-shaped bracket 55 is mountedthereon forv adjustment in a horizontal plane toward or -away from theperiphery of the form 44, as shown in Figure 9.4 .Upon the braclret .55a pair of tools 56 is mounted for adjustment in substantially a verticalplane. Each tool is fulcrumed, asat 58, uponthe bracket 55 for movementtherecu so that their forward ends may be swungllaterally of theforrn44. Each tool comprises a handle ,portion 56 anda vertical bladeportion 5Z. lThe. blade portion '57 of each-toolhas its forward endcurved and the tools are mounted so that their'under edges will engagethe surfaces 53 of the ring 47 when. said tools are swung upon theirful- Crum 58 to move the lblade portions vtoward up'o'n the "blades l57ina directionf-substan- 70 tially radial in respect to Itheform 44, asshown 1n Figure 10.

The form is nowrotated .once the devices previously described, or unti the strip 1overlaps its free end portion, whereupon the strip is out on the bias bymeans now to be described. i. y

The means for cutting or severing the strip is designed to clit with ashearing a9- tion, for instance in the manner of a palr of shears. Inthe present embodimentof my invention, I have elected to utilize such aninstrumentality, although other devices maybe substituted in lieuthereof as will be apparent. The'shears, designated 72 1n the drawings,are arranged intermediate the guide plate 62, and the form 44 inthe pathi of travel of the strip 1. One lade of the shears 72, preferably thelower one, is afxed, below thestrip 1, to a bracket 73 that projectslaterally from the support 68, as shown in' Figure 4 of thev drawings.The other blade of the shears projecting across and over the strip isarranged at an angle relative to the'strip. The handle portion 74 of theother blade of the shears 72 is piv oted in the lower end of avertically movable floating yoke 75 that is suspended from the upper endof the support 68 by a retraetile spring 76. A vertical pull rod 76connects the lower end of the yoke 75 to one end of -k a trip lever 77.The trip lever 77 is p`1v oted at itsopposite end to the v:bracket 54beneath the shaft 6 and transversely thereof,

, and is arranged so that its intermediate portion is directly below theshaft 6, being provided at its intermediate portion with anupstan'ding'fnger 78. A notched cam 79 is Iixed upon the shaft 6 inposition to engage thefinger 78. rThe cam 79 is constructed to depressthe l'ree end of 'the hlever 77 until the shaft 6 and forni 44 havelbeen rotated through a single cycle ot' movement, whereby `the yoke ispulledl downwardly with respect to the braeke&7i1'and the shears 72 heldin an open positionrNv Normally the free end of the lever 77 is latehedinra depressed position by means eta' vertically disposed trigger 8l.The trigger 81 is pivoted, as at '81, intermediate its length to swingabove the free end ot' the lever 77 and upon an arm 82 that extends'from the upright 5. The lower end of the trigger is notched, as at 83,to engage the t'rec end of the lever 77.I N rmally the trigger is heldin engaging position relative to the free end of the lever s 77 by meansof a retractile spring 84, one

lug 86 thatjis aiiixed to thebraeket 54.A

lVhen it is desired to sever the strip 1 after rotation of the form 44,the operator pulls A latch 88 is provided forvholding the trigger' 81 indisengaged position relative to the lever 77. The latch 88 comprises ahorizontal finger that is pivotedat one end to the trigger 81 above thepivotal point 81' thereof. The opposite end of the latch is providedwith a bayonet slot 89 which receives a pin 90 that projects laterallyfrom the arm 82. The slot 89 is constructed withl a vertical portion v91and a horizontal por- I tion 100. Normally when the trigger is inengaged position relative to the lever 77, the pin 90 engages thehorizontal portion 100 of the slot and permits the spring 84 to hold thetrigger in engaging position relative to said lever. When the trigger ismoved, however, to disengage it from the lever 77, the latch falls withthe vertical portion 91 of its slot engaging the pin 90A and the triggeris held in disengaged position relative lto the lever 77. As the notch87 of the cam 79 is rotated past the'finger 7 8, tlie'lever 77 is raisedby' the action of the spring 7 G and an abutment 101 on said lever 77engages the `free end of the latch 88 and moves it so that the pin 90may engage the horizontal portion of the slot 89. The spring 84 is nowfree to move the trigfer into engaging position relative to the ever 7 7By this means the shears are operated only once during the building of abead'and not until the operator again releases the trigger by actuatingthe rod 85.

After the form 44 has been rotated once and the strip l has been severedand overlapped in the manner shown in Figure 14, the rotation oL- theform 44 may be continued the desired number of times to wind the wiretape upon the fabric cover.,y I then attach the irce end of the strip 3,aie shown 1n Figure 15, and revolve the form'a third revolution,:ts-shown in Figure 16, the wire and filler being cut by the operatormanually. A portion of the edges of the strip l are next folded over theconvolutions of gage the circumferential portion of the structure. 1next revolve the form a fourth revolution, whereupon the pointed ends ofthe tools engage beneath the unfolded edges of the strip l and fold themagainst the si des of the uncovered convdllutipns. At the same time theshoes 59 fold the edges of the strip l over the top `of the uncoveredconloo In this posi-7' .tion ot the tools, the ironing shoes 59-encumferential portion of the structure.

The structure is now given a partial cureand molded into the form shown 1n Figure 22.

By mea-ns ofthe construction of my novel vform 44, I may substitutediderent sizes of annuli 47 for different-sizes of beads and center themaccurately relative to the axis of the form. Furthermore, the tools aremounted for adjustment in accordance with the size of the annulus usedand the ironing shoes are also adjustable upon the tools in a manner toproperly position them for different sizes ot beads.
